Polymorphonuclear leucocyte motility in patients with severe burns

Chemotaxis, chemokinesis and cellular orientation were measured for unstimulated and 10(-7) n-formyl methionyl leucyl phenylalanine (F-met-leu-phe) stimulated polymorphonuclear leucocytes (PMNS) of nine patients with recent 10-80 per cent burns using a computer-assisted image analysis technique. The technique records PMN movement, as viewed with a phase-contrast microscope on videotapes, and then uses computer programs to calculate the speed and direction of up to 50 PMNS over a 5-min period. Orientation was determined visually. Cellular adherence was also measured by attachment methods. PMNS from burn patients were slower (av. speed 16.8 microns/min), responded less well to F-met-leu-phe (av. speed 20.9 microns/min, av. McCutcheon index 0.32), were less often oriented towards the chemoattractant (av. 39 per cent) and were more adherent (av. 50 per cent) than control cells (av. speed 21.8 microns/min; av. speed F-met-leu-phe 32.2 microns/min; McCutcheon index 0.61; oriented 59 per cent adherent; 16 per cent). Thus PMNS from burn patients orient less well, are significantly slower and have less directionality in response to a chemoattractant, and are more adherent suggesting activation.     

Idiopathic hypereosinophilic syndrome terminating as disseminated T-cell lymphoma

The authors describe a case of idiopathic hypereosinophilic syndrome (HES) terminated as a T-cell lymphoma in a 3-year-old girl. The clinical course was chronic and characterized by chronic eczema, persistent peripheral blood eosinophilia, organomegaly, interstitial lung change, and pericarditis. Postmortem examination demonstrated a disseminated T-cell lymphoma involving the inguinal lymph node, liver, lung, and kidney. The findings of the current case suggest a possibility that certain abnormalities in this case of idiopathic HES per se may have triggered the development of malignant lymphoma, and it may represent a transition of idiopathic HES into a T-cell lymphoma. Other possible sequences are discussed. The development of T-cell malignancy in idiopathic HES in a girl is quite an unusual presentation.     

Cultural perspectives and current consumption changes of cooked rice in Korean diet

Cooked rice is a staple food for Koreans which provides more than 60% of daily required energy. In 1960''s, Koreans ate 600 g-800 g of cooked rice per meal and the energy obtained from cooked rice was almost more than 80% of the daily intake of energy. However, as the economy of Korea improved, the major industry has been shifted from agriculture to various manufacturing industries and the export of those products has been increased thus increasing the national income but decreasing the farming population and thus rice consumption have been decreased. It has been said that the decreased rice consumption is caused solely by decreased farming population but it can also be said that the decreased farming population is caused by decreased rice consumption.As the national income increases, the type of foods people consume have become diversified. Various processed foods such as convenience food or ready-to-eat food have been widespread, which are mostly made of wheat flour rather than rice.     

Localization of dystonic muscles with 18F-FDG PET/CT in idiopathic cervical dystonia.

The purpose of this study was to investigate whether (18)F-FDG PET/CT is useful for localizing dystonic cervical muscles in patients with idiopathic cervical dystonia (ICD) by comparing disease severity before and disease severity after botulinum toxin (BT) injection into hypermetabolic muscles. METHODS: Six patients with ICD underwent (18)F-FDG PET/CT. Dystonic muscles suitable for BT injection therapy were defined as those showing diffusely increased (18)F-FDG uptake. RESULTS: Hypermetabolic cervical muscles were identified in all 6 patients. In 2 patients who underwent PET/CT both in a supine position and in a sitting position during (18)F-FDG uptake, abnormal hypermetabolic muscles were observed by PET/CT only when patients were in the sitting position with their heads and necks in the adopted abnormal involuntary posture. Symptoms were significantly improved in 4 patients who underwent BT injection therapy guided by PET/CT and who were clinically monitored. CONCLUSION: (18)F-FDG PET/CT is potentially useful for identifying dystonic cervical muscles for BT therapy in patients with ICD.     

Spontaneous disappearance of a suprasellar arachnoid cyst: case report and review of the literature

Introduction Suprasellar arachnoid cysts are uncommon developmental anomalies that are most often diagnosed in childhood. Because the natural history and pathogenesis of these remain poorly defined, optimal treatment guidelines are not yet established.Case report We report a case of spontaneous disappearance of a suprasellar arachnoid cyst that persisted after a ventriculoperitoneal shunt performed 10 years earlier. A 5-year-old boy presented with impaired visual acuity and urinary incontinence. Magnetic resonance (MR) imaging showed a large suprasellar cyst with noncommunicating hydrocephalus. A ventriculoperitoneal shunt was put in place to alleviate current aggravation of hydrocephalus symptoms. Because of the persistent size of the cyst and signs of brainstem compression on a repeat computed tomography (CT), we recommended surgical exploration and decompression. However, the boy’s parents declined any further surgical treatment, and the patient was subsequently lost to follow-up for 10 years. When the patient returned to our clinic at the age of 15 years, a repeat MR scan showed a complete disappearance of the cyst. His family denied any significant interval history.Discussion This case represents only the third reported case of spontaneous disappearance of a suprasellar arachnoid cyst. We discuss possible mechanisms and clinical characteristics of the disappearance of the arachnoid cyst with review of the literature.     

Central Nervous System Lymphomatoid Granulomatosis Presenting with Parkinsonism

Lymphomatoid granulomatosis (LG) is a potentially malignant lymphoproliferative disorder. The lung is the most common involved site, followed by the skin and nervous system. However, LG of the central nervous system presenting with Parkinsonism is very rare. We report a patient with LG who presented with parkinsonian features such as bilateral rigidity, bradykinesia, and agitation. Brain magnetic resonance imaging showed multifocal punctuate enhanced lesions in both supra- and infratentorial areas. Steroid pulse therapy resulted in a dramatical improvement in the symptoms and MRI abnormalities.     

Providence School Asthma Partnership: School-based Asthma Program for Inner-City Families

Over 3 years, 972 families participated in an after-school asthma program at their child's school. Parents and children attended concurrent 2¹/₂ -hour workshops. Parents were 74% Latino; 45% non-English speaking, with 77% of children on Medicaid. Asthma symptoms were significantly reduced, from multiple times per week to less than once per week on average. Oral steroid use decreased to one third of baseline use. Hospital days decreased from 11% to 2%; emergency visits decreased 35% to 4%; and school days missed decreased 48% to 20%. This program has now become sustainable with both private and Medicaid insurance coverage.     

Determinants of health-service use by low-income people.

Poverty influences health status, life expectancy, health behaviours, and use of health services. This study examined factors influencing the use of health-related services by people living in poverty. In the first phase, 199 impoverished users of health-related services in 2 large Canadian cities were interviewed by their peers. In the second phase, group interviews with people living in poverty (n = 52) were conducted. Data were analyzed using thematic content analysis. Diverse health-related services were used to meet basic and health needs, to maintain human contact, and to cope with life's challenges. Use of services depended on proximity, affordability, convenience, information, and providers' attitudes and behaviours. Use was impeded by inequities based on income status. To promote the health of people living in poverty, nurses and other health professionals can enhance the accessibility and quality of services, improve their interactions with people living in poverty, provide information about available programs, offer coordinated community-based services, collaborate with other sectors, and advocate for more equitable services and policies.     

Cellular and Molecular Foundation for Fracture Healing in Children

Abstract Dealing with pediatric fracture patients requires a funded knowledge of complications and remodeling capability of the youth skeleton to find the accurate therapy decision and to avoid unnecessary invasive procedures. Due to the different mechanical environment, fractures in children occur at specific fracture-vulnerable areas. One of those is the growth plate, which on one hand gives rise to the unique ability of correcting angular deformities by specifically increasing the growth rate in definite regions, and on the other hand leads to complications like growth arrest or angular deformity. The pediatric diaphysis presents the exclusive greenstick fracture, only seen in the growing skeleton, which occurs because of the different composition of the pediatric bone. To understand these very specific features of the youth skeleton, the molecular and cellular basis should be taken into consideration. Therefore, this review will present the common characteristics of skeletal development and fracture healing. An insight into the mechanotransduction as part of the remodeling and self-correcting ability of pediatric bone is given to span the bridge between clinical treatment options and scientific background.
